Raspberry Pi 5 active cooling management settings - config.txt
by Exaga from LinuxQuestions.org on (#6PG2H)
Raspberry Pi 5 users FYI only - this info doesn't apply to any other version or model!
Those 'very smart people' over at Raspberry Pi Ltd. (yep, I'm intentionally being sardonic) have finally made it easier for end-users on the Raspberry Pi 5 to manage their active cooling fan settings and parameters... sort of. After a fashion.
Users can now manage these values via dtparam settings in the /boot/config.txt file - for a list of possibilities see the /boot/overlay/README file. Basically there's 3 options and 4 levels to play with:

How to implement it? Really easy. Edit the config.txt file by adding something like this:
Code:## Pi 5 active cooling fan parameters
# Cooling fan on | off
dtparam=cooling_fan=on
# Tepid: 40% fan @ 40'C
dtparam=fan_temp0=40000
dtparam=fan_temp0_hyst=3000
dtparam=fan_temp0_speed=100
# Warm: 60% fan @ 45'C
dtparam=fan_temp1=45000
dtparam=fan_temp1_hyst=4000
dtparam=fan_temp1_speed=150
# Hot: 80% fan @ 55'C
dtparam=fan_temp2=55000
dtparam=fan_temp2_hyst=5000
dtparam=fan_temp2_speed=200
# Very Hot: 100% fan @ 65'C
dtparam=fan_temp3=65000
dtparam=fan_temp3_hyst=5000
dtparam=fan_temp3_speed=255Alternatively, you can do it like this:
Code:## Pi 5 active cooling fan parameters
# Cooling fan on | off
dtparam=cooling_fan=on
# Tepid: 40% fan @ 40'C
dtparam=fan_temp0=40000,fan_temp0_hyst=3000,fan_temp0_speed=100
# Warm: 60% fan @ 45'C
dtparam=fan_temp1=45000,fan_temp1_hyst=4000,fan_temp1_speed=150
# Hot: 80% fan @ 55'C
dtparam=fan_temp2=55000,fan_temp2_hyst=5000,fan_temp2_speed=200
# Very Hot: 100% fan @ 65'C
dtparam=fan_temp3=65000,fan_temp3_hyst=5000,fan_temp3_speed=255NB: the above settings and values are my own, based on my Pi 5 usage and setup. Yours will most certainly be different so adjustments will need to be considered to factor in your personal preferences and test-case.
Back in December 2023 I fervently appealed to Raspberrry Pi Ltd. (on their forums) with what I thought was common sense and the logical thing to do... and ended up being perm-banned for it! The moderator's excuse was "signature spam" even though I'd been using the same signature for over a decade. It just makes me laugh so goddam hard when they end up doing EXACTLY what I suggested to them in the first place! PMSL :party: :D :doh:
[EDIT] I'll be including the above active cooler management settings in future SARPi5_64 releases.

| dtparam=fan_temp0 - Temperature threshold (in millicelcius) for level trigger. When the temp reaches this value it becomes active. e.g. 50000 = 50 degrees Celsuis. dtparam=fan_temp0_hyst - Temperature hysteresis (in millicelcius) for 1st cooling level. Fan will be active while cooling level is active i this value. dtparam=fan_temp0_speed - Fan PWM setting for 1st cooling level [0-255] - 0 = 0% | 255 = 100% - Fan will rotate at this value for the set cooling level. |
